Port forwarding aircard 810s not working

   Not a very detailed description of anything.  What are your actual
port-forwarding rules?  What are they supposed to do?

   The router's LAN IP address is different from its WAN/Internet IP
address.  I would not expect port forwarding to be effective when you
specify the router's LAN IP address.

> The only 2 ports that are open are, port 80 (DMZ enabled) and 53.

   Those would be the router's management web site, and its DNS server,
respectively.  Looks normal to me.

   Not really.

   _You_ might, but there's no evidence here that the router firmware
does.

   What's the IP address of the router's WAN/Internet interface?  Have
you tried testing that?

but, if you have other problems, you might find it helpful.)
